Efforts to flush out Baltimore City’s storm drain system after an oil spill Wednesday leaked 5,000 gallons of diesel fuel into the Baltimore Harbor have been effective, says the U.S. Coast Guard.

Many of the large pools of diesel fuel, noticeable by its distinct red color from dye, have been removed from Baltimore's harbor two days after a 2,000-gallon spill.

Maryland Governor said there was "no evidence" the 2,000-gallon diesel fuel spill in Baltimore's harbor was currently impacting drinking water.
